Methods and apparatus for data transmission

Abstract

Embodiments of the present disclosure provide methods, apparatus and computer program products for data transmission. A method implemented at PGW-C in a wireless network may comprise: determining that an additional user plane of the PGW for a PDN connection needs to be allocated, wherein the PDN connection is used by a user equipment (UE) to connect to a first data network through at least a user plane of a serving gateway (SGW) of the wireless network and an initial user plane of the PGW, and the additional user plane of the PGW is used for connecting with a second data network; selecting the additional user plane of the PGW; sending address information of the additional user plane of the PGW and instruction information to a control plane of the SGW, wherein the user plane of the SGW or the additional user plane of the PGW implements an uplink classifier function to enable a specified part of uplink data in the PDN connection to be forwarded to the second data network through the additional user plane of the PGW.
